🚀 Getting Started with Installation

To get started, you need to install the Web Browser MCP Server on your system:

Installation

Choose from one of these package managers to install the latest version:

# Using pip
pip install web-browser-mcp-server

# Using uv (recommended)
uv pip install web-browser-mcp-server

For developers who prefer a more controlled environment, cloning and running from source is also an option. First, create and activate a virtual environment:

uv venv
source .venv/bin/activate
pip install -e ".[test]"

Once installed, you can run the server using the following command line arguments:

uv --directory /path/to/web-browser-mcp-server run web-browser-mcp-server

Replace /path/to/web-browser-mcp-server with your installation directory. Optionally, add environment variables for customizing behavior such as REQUEST_TIMEOUT, USER_AGENT, and LOG_LEVEL.

💡 Key Use Cases in AI Workflows

The Web Browser MCP Server excels in various AI workflows:

Real-World Implementation: Information Extraction for News Aggregation

In this scenario, the Web Browser MCP Server is integrated into an AI application to scrape news articles from multiple websites. By utilizing CSS selectors and asynchronous processing, it efficiently extracts titles, authors, and summaries without loading the full content.

result = browse_webpage(url="https://example.com/news",
    selectors={
        "headlines": "h1, h2",
        "author": ".byline a",
        "summary": ".summary"
    }
)

Real-World Implementation: E-commerce Product Listing Automation

Another compelling use case involves automating product listings for e-commerce sites. By targeting specific content with CSS selectors and handling timeouts robustly, the AI application can collect structured data like prices, descriptions, and images.

result = browse_webpage(url="https://example-store.com/products",
    selectors={
        "product_title": ".product-name",
        "price": ".price",
        "image_url": ".thumbnail"
    }
)

These examples illustrate how the Web Browser MCP Server can be seamlessly integrated into AI workflows to enhance and streamline data collection processes.
